摘要:

制备了一种新型改性活性炭负载FeCl3催化剂(MAC-FeCl3),并通过红外光谱及等离子体发射光谱等技术手段对其进行了表征。 在MAC-FeCl3催化下,β-萘酚与醛在PEG200中,于120 ℃反应60~120 min,合成了一系列氧杂蒽类衍生物,收率为79%~93%。 该方法操作简单、产率高、环境友好。 制备的催化剂性能稳定,使用4次仍保持较高活性。

Abstract:

A novel modified active carbon supported ferric chloride catalyst(MAC-FeCl3) has been prepared and characterized by IR and ICP-AES. In the presence of MAC-FeCl3, condensation of aldehydes and β-naphthol was carried out in PEG 200 to afford a series of xanthene derivatives in 79%~93% yields within 60~120 min. The prepared catalyst can be recycled easily and the activity of catalyst maintains stable after used for 4 times. This affords this methodology the advantages on good yields, less pollution and simple work-up.

Key words: modified active carbon supported ferric chloride, xanthene derivatives, heterogeneous
